This volume brings together a collection of 18 papers that look into the expression of modality in the grammars of natural languages, with an emphasis on its manifestations in naturally occurring discourse. Though the individual contributions reflect a diversity of languages, of synchronic and diachronic foci, and of theoretical orientations — all within the broad domain of functional linguistics — they nonetheless converge around a number of key issues: the relationship between 'mood' and 'modality'; the delineation of modal categories and their nomenclature; the grounding of modality in interactive discourse; the elusive category 'irrealis'; and the relationship of modal notions and categories to other categories of grammar.

This highly illustrated and definitive dictionary, by two renowned biologists - one Kenyan, one Canadian - contains extensive coverage of the flora, fauna and animals of the Lake Victoria region of East Africa occupied by the Luo community, and is based on ten years of research by the authors. It is an expansion of the 1972 publication Luo-English Botanical Dictionary of Plant Names and Their Uses and now provides more botanical entries and an additional section consisting of a zoological dictionary. The individual entry comprises Luo terminology, its botanical/zoological equivalent, common name (when applicable), physical description, its prevalence, and its respective economic use.

This grammar of Kenyan Sign Language (KSL) phonology adds to a sparse literature on the units of categorical form in the world’s sign languages. At the same time, it brings descriptive and theoretical research on sign language phonology into better alignment by systematically evaluating current models of sign language phonology for each of the main parameters – handshape, location, and movement – against the KSL data. This grammar also makes a methodological contribution by using a unique dataset of KSL minimal pairs in the analysis, demonstrating that minimal pairs are not as infrequent in sign languages as previously thought. The main content of the book is found in five chapters on handshape, location, core articulatory movement, manner of movement, and other distinctive features (e.g., orientation, mouth actions). The book also contains two large appendices that document the phonological evidence for each of the 44 handshapes and 37 locations. This book will be a key reference for descriptive and typological studies of sign phonology, as well as a helpful resource for linguists interested in understanding the similarities and differences between current models of sign phonology and identifying promising avenues for future research.

This book is the outcome of several decades of research experience, with contributions by leading scholars based on long-term field research. It combines approaches from descriptive linguistics, anthropological linguistics, socio-historical studies, areal linguistics, and social anthropology. The key concern of this ground-breaking volume is to investigate the linguistic means of expressing number and countable amounts, which differ greatly in the world’s languages. It provides insights into common number-marking devices and their not-so-common usages, but also into phenomena such as the absence of plurals, or transnumeral forms. The different contributions to the volume show that number is of considerable semantic complexity in many languages worldwide, expressing all kinds of extendedness, multiplicity, salience, size, and so on. This raises a number of challenging questions regarding what exactly is described under the slightly monolithic label of ‘number’ in most descriptive approaches to the languages of the world.
